ABSTRACT
A tirmana is a phrase based on keeping the same distance between notes and decreasing this separation systematically. These distances can be turned into frames over which anuloma-pratiloma, in various forms, can be superimposed. In this context, the difference in construction between the purvanga and uttaranga sections of a tirmana sequence allows for different approaches as to which developmental technique and gati can be chosen to superimpose over the frames. Poruttam 'B' ultimately consists of short passages of highly intricate and complex material, due to the exclusive use of anuloma-pratiloma and the almost continuous displacement of irregular groupings within the beat. The choice of tisra is taken again for this possibility, in order for the last step to be performed with relative ease. The third step of the purvanga uses gati bhedam.
